.SH NAME
shtags \- Create tags for shell scripts
.SH SYNOPSIS
.B shtags
[\fI-mvw\fP] [\fI-t <file>\fP] [\fI-s <shell>\fP] <files>
.SH DESCRIPTION
\fBshtags\fP creates a \fBvi(1)\fP tags file for shell scripts - which
essentially turns your code into a hypertext document. \fBshtags\fP
attempts to create tags for all function and variable definitions,
although this is a little difficult, because in most shell languages,
variables don't need to be explicitly defined, and as such there is
often no distinct "variable definition". If this is the case,
\fBshtags\fP simply creates a tag for the first instance of a variable
which is being set in a simple way, ie: \fIset x = 5\fP.
.SH OPTIONS
.IP "\fB-t <file>\fP"
Name of tags file to create. (default is 'tags')
.IP "\fB-s <shell>\fP"
The name of the shell used by the script(s). By default,
\fBshtags\fP tries to work out which is the appropriate shell for each
file individually by looking at the first line of each file. This won't
work however, if the script starts as a bourne shell script and tries
to be clever about starting the shell it really wants.
.b
Currently supported shells are:
.RS
.IP \fBsh\fP
Bourne Shell
.IP \fBperl\fP
Perl (versions 4 and 5)
.IP \fBksh\fP
Korn Shell
.IP \fBtclsh\fP

.RE

.IP \fB-v\fP
Include variable definitions (variables mentioned at the start of a line)
.IP \fB-V\fP
Print version information.
.IP \fB-w\fP
Suppress "duplicate tag" warning messages.
.IP \fB-x\fP
Explicitly create a new tags file. Normally new tags are merged with
the old tags file.
.PP
\fBshtags\fP scans the specified files for subroutines and possibly
variable definitions, and creates a \fBvi\fP style tags file.
.SH FILES
.IP \fBtags\fP
A tags file contains a sorted list of tags, one tag per line. The
format is the same as that used by \fBvi\fP(1)
